The second-season premiere of “MasterChef Junior” helped bring some energy to Fox’s Tuesday lineup, as it more than doubled what the net had been doing earlier this fall in its timeslot with “Utopia” and helped provide a much-needed lift to the comedies airing in the 9 o’clock hour.

It was an aytpical night, as not only were Election Night updates sprinkled throughout on local stations (which makes the prelims subject to more revision than usual), but the “NCIS” shows were in repeats, “The Voice” aired a recap special and ABC didn’t air “Marvel’s Agents of SHIELD.”

ABC, CBS and NBC devoted the 10 p.m. hour to Election Night coverage, but didn’t generate a lot of interest, based on the preliminary affiliate-based nationals. CBS and NBC both did a 1.3 rating in the key news demo of adults 25-54, with ABC at 1.1. And in total viewers, the nets combined for about 13 million viewers (with CBS leading the way).

On the entertainment side, “MasterChef Junior” averaged a series-high 1.8 rating/5 share in adults 18-49 and 5.1 million viewers overall in the 8 o’clock hour, placing a competitive second in 18-49 to NBC’s “Voice” special “The Road to The Live Shows” (2.3/7 in 18-49, 9.5 million viewers overall) — the night’s top program in 18-49. “MasterChef Junior” opened to a 1.6 demo rating on Friday last fall and proved to be an especially strong performer in DVR playback.

When it was clear that “Utopia” wasn’t cutting it on Tuesday, Fox gave “MasterChef Junior” (originally planned to air again on Friday this fall) a timeslot upgrade to take its place.

The 1.8 season-premiere rating is more than double the 0.8 that “Utopia” averaged in its two Tuesday airings during the television season.

The Gordon Ramsay cooking contest was followed by “New Girl” (1.6/5 in 18-49, 3.4 million viewers overall), which shot up 33% from its prior original before taking two weeks off for the World Series and posted its best score since its Sept. 16 premiere (1.7). It leapfrogged over NBC’s declining “Marry Me” (1.3/4 in 18-49, 5.0 million viewers overall), which had received a considerably higher lead-in than previous weeks.

Similarly at 9:30 p.m., Fox’s “The Mindy Project” (1.3/4 in 18-49, 2.9 million viewers overall) matched its premiere score and pulled ahead of NBC’s “About a Boy” (1.1/3 in 18-49, 2.9 million viewers overall).

At ABC, rookie comedy “Selfie” didn’t do itself any favors by regressing to a 1.0/3 and 0.9/3 with its back-to-back originals (with the hour averaging about 3.7 million total viewers); the 0.9 at 8:30 p.m. at least was an improvement over “Manhattan Love Story,” which was axed after falling to a 0.7.

“Selfie” was followed by the modestly rated special “Marvel: 75 Years, From Pulp to Pop” (1.2/3 in 18-49, 3.9 million viewers overall).

CBS switched up the order of its dramas as they shifted into repeats, with “NCIS: New Orleans” doing a 1.4/4 in 18-49 and 10.0 million viewers overall at 8, and “NCIS” following with a 1.5/4 and 11.7 million. “NCIS” edged out the Fox firstrun comedies in 18-49 for the 9 o’clock hour while standing as the night’s most-watched program overall.

CW aired repeats of both “The Flash” (0.6/2 in 18-49, 1.9 million viewers overall) and “Supernatural” (0.5/1 in 18-49, 1.3 million viewers overall).

Preliminary 18-49 averages for the night: Fox, 1.6/5; NBC, 1.5/4; CBS, 1.2/4; Univision, 1.1/3; ABC, 1.0/3; CW and Telemundo, 0.5/2.

In total viewers: CBS, 9.0 million; NBC, 6.1 million; Fox, 4.1 million; ABC, 3.7 million; Univision, 2.6 million; CW, 1.6 million; Telemundo, 1.3 million,
